EXTENSION-TABLE.

SPECIFICATION forming part of Letters Patent No. 316,472, dated April28, 1885.

Application filed June 18, 1884.

T0 aZZ whom it may concern.-

Be it known that I, Josnua D. DLIAIN, of the city of Springfield, countyof Clark, and State of Ohio, have invented certain new and usefulImprovements in Extension-Tables, of which the following is aspecification.

This invention relates to extension-tables, and is especially intendedas an improvement upon that class wherein the legs are made removable.

The object of my invention is to provide an extension-table which willbe cheap and durable in construction, and in which the extension-railsor slide-bars will be connect ed directly with and slide in the siderails of the table, said side rails forming a part thereof, therebyproviding a bearing for the leaves of the table in close proximity totheir ends; also, to so construct the legs of the said table that theymay be easily removed and replaced, which is of great convenience inshipping, 860.

Figure 1 represents an under side sectional view on dotted line at as,Fig. 2, of an extension-table made in accordance with my invention, theside rails being herein shown on a line with one another and providedwith supplemental extension-rails; Fig. 2, a side elevation ofthe same,partially in section; Fig. 3, an enlarged detail of the clampingmechanism for holding the legs in place; Fig. 4, a detail ofthe siderails and corner-posts, the said rails being herein shown as overlappedand connected directly with one another; and Fig. 5 is a section ondotted line 3 y, Fig. 1, of the extension 'rails.

The table-top, of any desired construction is composed, as usual, of twomain sections, A A, andleaves B.

Attached to the under side of the tabletop sections A A are corner-posts0, said corner-posts being connected together by end rails, D D, siderails, D D and supple mental extension-rails D D D, the said side railsand supplemental extension-rails being herein shown as connectedtogether by means of tongues and grooves. The extension-rails D D areconnected together by means of a cross-bar, E, said crossbar E having anopening at its center for the reception of the center leg, F, of thetable. The corner-posts O are bored out to form a recess to receive (Nomodel.)

round tenons or dowel-pins G on the legs H,

extensiontable-say an eight-foot table-the side rails, D D", will bemade, as shown in Fig. 4:, to overlap one another, thereby d0- ing awaywith the supplemental extensionrails D D D", the corner posts 0 being insuch case recessed to form an opening for the reception of the oppositeside rails. This, as will be noticed, forms a very simple and convenient extension, and there being no joint or scam in the center of theside rails when the table is closed adds materially to theornamentation.

By the construction herein described a bearing is formed for the leavesof the table in close proximity to their ends, which is a greatdesideratum, as it insures a greater rigidity of parts than if asheretofore constructed, the extension in tables of usualconstructionbeing near the center of the table.

I claim- In an extension table, the combination, with the corner-postsand removable legs, of the clamping device for holding the legs inplace, consisting of the binding post 1, secured to the corner-posts,the spring-clamp K, having the elongated slot J, said springclamp beingadapted to engage with the leg, as described,and the thumb-nut 1* toregulate the tension of the spring-clamp, substantially as described.

In witness whereof I have hereunto set my hand and seal, at Springfield,Ohio, this 8th day of June, A. D. 1884.

JOSHUA D. MAIN.
